Abstract

A temperature-controlled mixer valve contains a disk control for determining the quantity of mixed water flowing out of the valve. To the disk control is connected a regulating unit, which determines the mixed water temperature. The control disk is movable with respect to the fixed distributor disk in a first degree of freedom for determining the mixed water quantity. By control disk movement in a second degree of freedom, the desired temperature of the thermostatic valve is modified.

Claims

1. Temperature-controlled mixer valve, comprising:

2. Mixer valve according to claim 1, wherein the regulating unit has an axis that is parallel to the control surface.

3. Mixer valve according to claim 2, wherein the regulating unit axis is at right angles to a direction of a closing movement of the movable control disk for controlling the mixed water quantity.

4. Mixer valve according to claim 1, wherein the regulating unit is moved together with the control disk.

5. Mixer valve according to claim 1, wherein the movable control disk is movable in the second degree of freedom by the regulating unit in response to the mixed water temperature and is also movable in the second degree of freedom by adjustment of the operating device.

6. Mixer valve according to claim 1, wherein the movement of the control disk in the second degree of freedom does not change relative sizes of alignable openings for cold and hot water through the fixed distributor disk the movable control disk.

7. Mixer valve according to claim 1, wherein the operating device moves the movable control disk in a second movement direction according to the second degree of freedom, for modifying the setting of the desired temperature of the temperature-controlled mixer valve.

8. Mixer valve according to claim 1, wherein the operating device comprises a device for setting an adjustment of the desired temperature.

9. Mixer valve according to claim 1, wherein the regulating unit is positioned in such a way that at least one of a mixed water outlet and an extensible material element of the regulating unit is located, in a flow direction, between a valve seat for hot water and a valve seat for cold water.

10. Mixer valve according to claim 1, wherein the regulating unit is located on the movable control disk.

11. Mixer valve according to claim 1, wherein the regulating unit is located in a dog affixed to the movable control disk.

12. Mixer valve according to claim 1, wherein no seal is provided between the two valves.

13. Mixer valve according to claim 1, wherein the regulating unit comprises a thermostat with an extensible material element and a control bush.

14. Temperature-controlled mixer valve comprising:

15. Mixer valve according to claim 14, wherein the component operatively connected to the regulating unit comprises an adjusting cap that is rotated to adjust the movable control disk.

16. Mixer valve according to claim 14, wherein the eccentric surface is formed on an inner wall of a cartridge casing of the mixer valve.

17. Mixer valve according to claim 16, wherein the eccentric surface is formed by a slider located on the inner wall of the cartridge casing.

18. Mixer valve according to claim 17, wherein the slider is constructed in such a way that it can be circumferentially adjusted.

19. Mixer valve according to claim 15, wherein the adjusting cap is operatively connected to the regulating unit in such a way that during a movement of the control disk in a quantity change direction, there is no adjustment of a temperature setting of the regulating unit.

20. Mixer valve according to claim 15, wherein the regulating unit engages with a tappet in a groove in the adjusting cap extending in the quantity change direction.

21. Mixer valve according to claim 14, further comprising an adjusting cap for relatively adjusting the regulating unit and the eccentric surface.
